Well, kind of. Remember that these are some really smart kids. The salary mentioned in the salary is equivalent to $10,000 p.a (@exchange rate of 1$ = 60 rupess). Not a lot of money at all.
That's a pretty stupid way to look at it. Compare it with salaries in India, not with USD. It's a lot of money (vs a young Software Engineer in India) if you live in a government sponsored apartment, and get other government benefits too.
That's the equivalent of $50000 in Purchasing Power; so it's not as bad. Although to be fair, a lot of commodities appear to cost a lot more in India, because they are tied (legally or otherwise) to the outside world (blame Indira and her kin!).
I've done a lot of work with the Indian government, and yes it can be very corrupted. But from what my friends at ISRO have told me -- and I believe them -- it is a meritocracy of the highest order. Its consistently excellent performance over the years is further testimony to this. ISRO should be an inspiration to the rest of India.
